I've just attended the TSM Implementation course. The number of deltas was quoted to be only 20. Can this number be modified? I intend to use adaptive backup to backup user data on the flock of PCs and Apples. The users may use either dial-up lines or LAN. Is there a method for checking beforehand whether the current backup session is going to be a base or a meta backup? This info would be used to prevent - or at least warn the user to not to use diap-up lines for huge backup sessions.
